I don't think rush is washed up, I think it was just motivational issues towards the end of C9. Plus he's a major winner, after all. He's experienced and can be a good support. But if you don't want him, there's probably an alternative. Maybe s0m, but idk if you want 3 really young players on the team. Or infinite? Isn't he an IGL? Then dephh could start fragging again.
But floppy has more experience than oBo did before he joined and seems to be carrying Singularity, so why not him?
Or they could get some international players.
